In this type of filtration, membranes with specific pore sizes can be used. However, clogging of filters is a major limitation. There are two types of membrane filtrations—static filtration and cross-flow filtration (Fig. 20.3). In cross-flow filtration, the culture broth is pumped in a crosswise fashion across the membrane.

Froth Flotation
A run-away is a frightening experience for a novice flotation operator. Froth begins to flow from the surface of the cells at such a rate that launder water sprays cannot break down the froth and it then begins to overflow the launder depositing on the sump floor. Even by dropping the cell level, the froth continues to flow and cannot be stopped.

Upthrust and Law of Floatation
Therefore, the relationship between upthrust and the real weight of a body is that while floating, the real weight of the body is equal to the upthrust exerted by the fluid.The above result leads to the Law of Floatation, that is, a floating body displaces its own weight of the fluid in which it floats.
